State-of-the-art of OFDM signals PAPR reduction 

OFDM Peak To Average Power Ratio (PAPR)

A major drawback of orthogonal frequency division multiplexing (OFDM) is the high peak-to-average power ratio (PAPR) of the transmitted signal. We just published a didactic overview of the main methods to reduce the peak to average power ratio (PAPR) of OFDM signals. This overview includes:

• Clipping and Filtering
• Selective Mapping (SLM)
• Interleaving
• Partial Transmit Sequence (PTS)
• Coding
• Tone Reservation (TR)
• Tone Insertion (TI)
• Active Constellation Extension (ACE)
• Constant Envelop OFDM (CE-OFDM)
• OFDM/TDM
• Carrier Interferometry OFDM (CI/POCI-OFDM)
